3D Math for Games

Master the math behind movement. Vectors, Quaternions, Matrices, and Dot Products explained visually for game developers.

Don't fear the math. This course visualizes Linear Algebra concepts essential for 3D graphics and gameplay. You will learn to use Vectors for movement and direction, Dot Products for field-of-view detection, and Cross Products for finding perpendiculars. We demystify Quaternions for smooth rotations (no gimbal lock!) and Matrices for coordinate transformations. Essential knowledge for graphics programmers and technical artists.
